To aZZ whom z' may' concern.

Be it known that l, HERMAN A. Porren- HUSEN, a citizen of the United States, residing at Hammond, in the county of Lake and State of Indiana, have invented new and use- :tul improvements-in Fire Arches, of which the following is a specification. i This invention -relates to tire-arches for furnaces and more particularly to fire-arches l@ made oi rows of tiles suspended from a framework or upper structure.

rll`he object ot my invention is to provide means for closing or sealing the joints between the tiles and the spaces between the l@ tiles and the supportingstructure for prevent-ing cold air being drawn into the combustion chamber down through the arch. lin the accompanying drawingslFig. 1 is a longitudinal vertical sectional view taken through a fire-arch provided with an air seal means in accordance with my invention; and

. Fig. 2 is a fragmentary transverse sectional view taken on line 2-2 oir Fig. 1. The fire-arch shown in the drawings comprises a plurality of blocks or tiles l, l arranged in rows extending at an inclination upward and inward from the front wall ot `the furnace setting, as usual in structures ot this character. As illustrated in Fig. l, the tiles l in each row rest one against the other and have Contact throughout their engaging front and rear fiat faces. ln cross-section the tiles l are shaped substantially as shown 35 in Fig. 2, there being spaces 2 between the several rows of tiles. These spaces 2 have the shape of inverted Vs, the tiles in lone row contacting sidewise with the tiles in the adl jacent rows at the vertexes ot said Vs. t@ Abovethese points of contact, the tiles have channels or grooves 3, 3 in their side faces to receive the base flanges 4 of the interposed -beams 5 which project above'the tops ot' the tiles, as shown. 'lhe'shoulders 6 'formed at the sides of the tiles along the tops ot the channels rest on the base flanges 4 of the il-beams and cause the tiles to be suspended therefrom, as shown. The tiles made and mounted as shown are tree to move relatively to each other about their points oit Contact as the temperature thereof varies while the furnace is in use.

The upper structure for the hre-arch, in addition to the l-beams 5, comprises a plurality of vertically arranged channel members 7, 7 located above the tiles and extend ing transversely across the arch between and supported by the side walls (not shown) of the furnace setting. The members 7 are spaced apart laterally, and engaging the base flanges thereof are hook-shaped members 8, 8,- several foreach -beam. `rlhese depend from said channel members 8 and engage about the .enlarged head portions ot the 1li-beams 5 for bestos or other heat resistant iiexible matef rial.

Each sheet 9 has a width to extend between the tbeams between which it is located with its side marginal portions 10, l0 against the adjacent sides of the ltbeams 5, 5 above the tiles and engaging under theheads @o ot said li-beams, as indicated in Fig. 2. This closes or seals the spaces between the l-beams and the tiles and also the joints between the tiles and prevents cold air above the arch. from being drawn through the same into the 35 combustion chamber therebelow by the suction on said combustion chamber.

To insure that the i layers will be mainn tained in flat contact with the tiles l and the lli-beams 5, 5, l place on said layers a packing of sand or otherA equivalent loose material 1l. lin each of the spaces between the Ill-beams 5, 5 there are a number or these erible layers or sheets 9, and these overlap ,at their meeting edges, as shown in Fig. i. The Suc- @5 tion on the arch from below also aids in holding the sheets against the .tiles and beams.

ln the archstructure shown in Fig. l, a tile or block la at the end of each row adj al cent the front wall of the furnace setting om l0@ tends below the tiles in that row to provide a step in the under side'or heat radiating surface of thearch to prevent cold air drawn into the combustion chamber through the inlet opening for theptue'l foilowng along and 405 chilling that surface, as set'torth in the ending application ot rhornas A. Marsh, erial No. 258,845, and tiled @ctober 19, 1918. The

j application.

insana-i "titles i. are snspended'in suchpositions troni the .it-beams 8 by adapter plate 83' asin said lWhile l have shown and described l in in detail one form of ineansernbof b y.the features of my invention, it is to oe of the passage ot air down through the arch' between said tiles, and a backing of loose material on said sheets for holding the same against said tiles.

2. In a VFre-arch. two laterally spaced beams, `a row of tiles between said beams and suspended therefrom, said tiles being in contact with each other, and a flexible sheet on said tiles and extending over the joints between the same, said sheet having its side margins in Contact with theportions 'of said beams proj eating' above said tiles tor closing the space between said tiles'and said beams.

ln a lire-arch. two laterally spaced beams, a row of tiles between said beams and suspended therefrom, said tiles being in contact with each other, a flexible sheet on said tiles and extending over the joints between the saine, the side margins of said sheet beari against the side portions of said beams closinrf the spaces between the same and tiles, and a packing of 'loose material sheet between said beams for holdin d sheet against said tiles and b earn --areh, two laterally spaced suspended therefrom, said tiles being` i edges tothe beams and there engaging the beanisa row of tiles between said beams and tact with each other, a plurality ott r sheets on said row o1C tiles and oyerlappiig at their meeting edges, said sheets extent' over the joints between said tiles andi their side margins against said bea closing the spr ces between said tiles beams, and a packing ot loose maten said sheets between said beams for ho 1 said sheets overlapped and in contact with said tiles and beams.

5. A re-arch,comprising a pluraliy eontacting tilesarrang'ed in rows, bea' tween the rowsof tiles and engager with for suspending the same, sain projecting above the tiles, and layosheet material over the tiles and between. the beams, said layers covering the. joints between the tiles and extending at their si the tiles same for closing the joints between and beams.

6. A fire-arch, comprisingy a plurality of contacting tiles arranged in'rows, beams tween the rowsor' tiles and engaged thereH with for suspending the same, said beams projecting above said tiles, sheets o ilexible material laid on the tiles between the beanie for covering the joints between 'the tiles.4 said sheets extending to the associa beams and having their side margins oi, i 'U5 lapping. the same7 and loose material laid on the sheets to hold the same on the tiles ard their side margins in Contact l beams, said loose material being held in place by the portions of the beams project ing above" the tiles.
